RIM FOR GRAND PIANOS.

Specification of Letters Patent.

Application filed March 30, 1910.

Patented Nov. 25, 1913.

Serial No. 552,450.

To all whom it may concern Be it known that I, JULIAN T. MAYER, acitizen of the United States, residing at New York, in the county of NewYork and State of New York, have invented a new and useful Rim for GrandPianos, of which the following is a specification.

This invention relates to the rim of a grand piano which forms the outercurved frame or body. In practice this grand rim is made of a number ofveneers and bent to the proper sinuous form which is required by theshape of the frame of a grand piano. This is a very expensive operationand requires a great deal of room in the factory, and only materialhaving a uniform grain throughout its length can be used.

The principal objects of this invention are to provide a construction inwhich the rim can be made in such a way that the parts thereof can bemanipulated in a comparatively small space in the factory and in whichthe same piece will not have to be subjected to such a great degree ofbending in opposite directions as has been the case heretofore; toprovide a construction in which shorter pieces of wood can be employedthus reducing the expense of the material; and to provide a constructionin which the rim will be ornamented by vertical lines upon its face.

Further objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawings in which,

Figure 1 is a plan of the rim of a grand piano constructed in accordancewith this invention, and Fig. 2 is a fragmentary elevation of a portionof the same.

When constructed according to this invention, the rim of the pianoinstead of being made in a single piece as heretofore, is formed of aplurality of pieces a, I), c, and d. These pieces are formed withrabbeted joints at their ends, each piece having an outer flange eforming part of the joint and overlapping a similar inner flange f onthe next piece. These flanges are of substantially half the thickness ofthe rim at that point. Each joint also has an overlapping outer edge eby means of which the rabbeted joints can be made very strong and at thesame time a handsome vertical line is caused to appear at the end ofthis overlapping edge giving an appearance of fine finish and strongconstruction to the piano body. In this way it will be seen that bydividing up the rim as has been stated, the instrument is given a richerand more attractive appearance in spite of the fact that theconstruction is materially cheapened, both in the cost of material andlabor.

It will be understood that the parts are glued together at the rabbetedjoints and that these joints can be located in various differentpositions. W'hen located in the places indicated in Fig. 1, two of themembers of the rim, a and d, are perfectly flat and all the curve comesin the other two which are divided at a place between two curves,leaving the piece I) with a comparatively short double curve. In thisway this piece can readily be manipulated to produce this curve, Withoutrequiring any great amount of room for the heating and bending and onlycomparatively short pieces having the best uniform grain have to beselected, and in fact the pieces a and cl need not be especiallysuitable for bending at all.

WVhile I have illustrated and described only one preferred embodiment ofthe invention, I am aware that changes can be made therein by any personskilled in the art without departing from the scope of the invention asexpressed in the claim. There fore, I do not wish to be limited to allthe details of construction, nor to the location being of greaterthickness than the distance i my hand, in the presence of tWOsubscribfrom the outer surface of the inner overing Witnesses. lappingportion to the outside of the piece from Which it projects so as toproject be- JULIAN MAYER 5 yond the surface of the next piece to formWitnesses:
